This sliver takes place in an alternate past, at the moment that the Eth High Priest Arakhurn and his acolytes first opened the Planar Gate at Passage of the Ancients. In this timeline there was an unforseen complication... forces of The Wanton had sabotaged the Planar Gate and, instead of opening to the Earth Plane of the Titans it opened on the Plane of Fire.

The portal into this instance is in the very west of Stonefield, at the mouth of the path into The Last Valley. Of course, Omen Sight or Quantum Sight is required to lead your raid into, or even see, the portal.

The following information is from the PTS and should be considered VERY preliminary. All of this may change before this instance goes Live (presumably with 1.6).All Boss notes and strategies can be found on the boss' individual mob page.

The Planar Gate

Passage of the Ancients

Three waves of mobs will emerge from the Planar Gate before Ereandorn.

Rescue the five Bahmi Priests from the cages along the way. They will be needed for the next boss as each can save you from one Incinerate. However, there is an achievement for downing the next boss without them!
